TPTBusiness 849a14185a fix(auto-fixer): strip spurious .reset_index() after .transform() calls ...

LLM sometimes copies the .reset_index(level=N, drop=True) suffix from
groupby().rolling().method() patterns and adds it after .transform(),
but transform() already preserves the original index. The extra
reset_index() drops an index level and causes ValueError: 'cannot reindex
on an axis with duplicate labels' or shape mismatch on assignment.

Detect: any line containing both .transform( and .reset_index(level=..., drop=True)
Fix: strip the .reset_index() suffix from those lines.

Adds 1 new test (test_transform_reset_index_stripped) — total 30 tests.
